DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to structures mainly composed of adjacent concrete walls, such as wall-to-wall, roof-to-roof, wall-to-roof, floor-to-floor, floor-to-wall, or ceiling-to-ceiling. Regarding expansion joints installed in gaps, the purpose is to provide an expansion joint that can cope with relative movement due to expansion or contraction of buildings due to changes in external forces and ensure watertightness. The purpose is to provide joint points.

Next, an embodiment of the present invention will be explained with reference to FIG. 1. In the figure, 41 indicates a wall W of an adjacent building.
1, the gap T between W1' (also called the skeleton)

D is formed. Further, at the other end of the web 45A, a projecting piece 45E is formed that corresponds to the guide piece 44G of the mounting member 44 and pinches and guides the sliding member 46.

46 is a sliding member, which is an inner sliding member 46A.
and an outer sliding member 46E, both of which are made of flexible spring steel or the like. This inner sliding member 46A is disposed at a predetermined interval along the fixing members 42 and 43, and a mounting convex portion 46C is formed approximately in the center of the web 46B, and both ends thereof are arranged at predetermined intervals. It is inserted into the space formed by the mounting member 44 and the lid member 45, and an engaging piece 46D is provided at the end.
is formed in a curved manner. In addition, the outer sliding member 4
Almost both ends of 6E are connected to the fixing members 42, 43.
The web 46F is formed to a length that allows the cover member 47 to be elastically engaged, and the web 46F has a substantially hook-shaped locking protrusion 46G extending upward in the drawing at both ends thereof. is formed.
The inner sliding member 46A and the outer sliding member 46E formed in this way are located at the mounting convex portion 46C at approximately the center of the gap between the skeletons W1 and W1'.
The fixing member 42,
A sliding member 4 that holds the lid member 45 of 43 from the inside and outside.
6 is formed, and the entire sliding member 46 is formed to be elastically deformable.

47 is a cover member of the joint 41,
It is made of a molded material extruded from a light alloy material such as aluminum, and is formed into a long length. In its cross section, 47A is a web provided almost horizontally, and the web 45A of the lid member 45 is attached to both ends of the web 47A. A groove portion 47B is formed in which the cushion member 28 is slidably guided and fitted into the cushion member 28. Further, a protrusion 47C that engages with a locking protrusion 46G of the sliding member 46, that is, the outer sliding member 46E, is formed in a part of this groove 47B. The sliding member 46 formed in this way has an inner sliding member 46A slidably sandwiched between the mounting members 44 of the fixing members 42 and 43 and the lid member 45, and the outer sliding member 46A.
6E is located on the upper surface side of the fixing members 42, 43, and is configured such that the cover member 47 is elastically engaged via a locking protrusion 46G.

The mounting members 44, 44 of the fixing members 42, 43 formed as described above are arranged in a connected manner along the outdoor surfaces of the walls W1, W1', respectively, as shown in the figure, and are fixed with mounting bolts. There is. A sliding member 46 is horizontally suspended at a predetermined interval between the mounting members 44, 44 disposed in this way, and lid members 45, 45 are formed at the ends of the mounting members 44, 44, respectively. The mounting pieces 45B, 45B are inserted into the grooves 44D, 44D of the mounting members 44, 44, and the locking portion 45C and the surface 44F are engaged and assembled integrally, so that the mounting pieces 45B, 45B are inserted between the fixing members 42, 43. The inner sliding member 46A is connected to the guide piece 44G and the protruding piece 45E.
It is clamped so that it can move in the left and right directions in the figure. The outer sliding member 46E is the fixed member 4.
The sliding member 4 on the upper surface side of 2 and 43 and on the same inner side
6A and the outer sliding member 46E are connected to the frame W1,
At approximately the center between W1', the mounting convex portion 46
The cover members 47 are welded and connected together in parallel by connecting means such as screw means, and the cover member 47 is elastically engaged through the locking protrusions 46G.

Therefore, the sliding member 46 is formed so that its entirety can be elastically deformed, and is slidably interposed in the lid member 45 between the fixing members 42 and 43 in a sandwiched manner. Even if the building expands or contracts and moves relative to each other in the direction (horizontal direction in the figure) due to changes in external force and the gap T1 changes, the entire joint 41 maintains its expansion and contraction state and closes the gap T1.
is shielded by a cover member 47. Also,
When the building relatively moves in the direction of the broken line arrow shown in the figure (up and down direction in the figure), since the entire sliding member 46 can be tilted and deformed, the cover disposed over the entire joint 41 tilts in accordance with the relative movement. The member 47 can also be held stably to cover the gap T1.

Note that the means for connecting the sliding member and the cover member is not limited to the structure of the above embodiment, but may be screwed or the attachment structure shown in FIGS. 2 and 3, for example. That is, the sliding member 71 shown in FIG. 2 has a protrusion 7 approximately at the center of its web 71A.
1B is formed, and a portion of the sides 71C, 71C of this convex portion 71B are cut and raised as shown in the figure to form locking pieces 71D, 71D, and the cover member 72 is attached to approximately the center of the web 72A. Projecting pieces 72B, 72B having a substantially hook-shaped cross section that engage with the locking piece 71D are arranged oppositely and engaged and connected. Further, the sliding member 73 shown in FIG. 3 is made by cutting and bending the web 73A symmetrically from the center of the web 73A as shown in the figure, and bending both cut and bending parts into a hook shape to form an engaging piece 73.
The web 73A and the engaging piece 73B are both formed to be elastically deformable. On the other hand, a protruding piece 74B having a substantially hook-shaped cross section facing oppositely (facing outward) to the protruding piece 72B of the cover member 72 described above is provided at approximately the center of the web 74A of the cover member 74. The sliding member 73 and the cover member 74 are connected by elastically engaging the engaging piece 73B.

As described above, the present invention provides a mounting member disposed in the gap between the frames of buildings adjacent to each other with an appropriate gap therebetween, and a lid that closes the outside of the mounting member and forms an appropriate space inside. A fixing member consisting of two members is disposed opposite to the fixing member, and an outer sliding member disposed across both fixing members and this outer sliding member are disposed outside the lid member of both fixing members. a cover member attached to the outside of the building frame to shield the gap between the building frames; the outer sliding member and the inner sliding member inserted into the space inside the lid member;
The lid members are connected at approximately the center of the gap between the skeleton bodies by appropriate connecting means, and the lid member is sandwiched between the inside and the outside by sliding members on the inside and outside, so that the lid member can be slid in the direction of expansion and contraction of the gap between the skeleton bodies. Since the structure is configured such that it is possible to cope with expansion and contraction fluctuations due to changes in external forces of adjacent buildings, it is possible to cover gaps between buildings in a stable state, and
Its watertightness can be improved.

Furthermore, the outer sliding member and the inner sliding member inserted into the space inside the lid member are connected by appropriate connecting means at approximately the center of the gap between the skeletons, and the inner sliding member and the inner sliding member inserted into the space inside the lid member are connected by appropriate connecting means. Since the lid member is held between the inside and outside by the sliding member,
The cover member can be easily attached to the lid member of the fixing member, and the ease of assembly of the entire expansion joint can be greatly improved.
